Hi,

When I simulate my model in a time interval with defined time step, i.e. range(0, 1e-3, 1), the solver automatically drops many nodes and only report solutions for a few time points. How can I enforce the solver to report solutions for each time step that I define?

Thank you very much for your help.

With the range command you define the time interval of your study. In your case that's from 0s to 1s. The value in the middle is NOT the time step of the time dependent solver. It is a time step at which the solver saves a solution. In your case you should get a solution every 1ms which you can access in the post processor.

You can change the settings like time step and the solver itself under the solver node for the Time dependent solver.

Got it. Thank you very much.
